ABSTRACT:
A digital voltage regulator for an electrical power system including a permanent magnet generator (PMG), an exciter, and a main generator. A controller multiplies the frequency of the generator output voltage by a predetermined value to provide a sampling signal having the multiplied frequency and synchronized with the generator output voltage. The controller also provides a sawtooth voltage signal having a repetition rate equal to the frequency of the sampling signal and an incrementing rate determined by the system clock signal. The generator output voltage is sampled at the frequency of the sampling signal. When the difference between the sampled signal and a reference voltage is greater than the sawtooth voltage, the PMG voltage is switched to provide voltage for the exciter field winding.
